According to a new study, gravity waves, mysterious waves that ripple unseen throughout the atmosphere, may be a major source of airplane turbulence. Yep, gravity, the source of all my weight and aging problems, is now found to be hitting airplanes in waves (like water). Gravity waves in the atmosphere can amplify and break , and it’s been determined that’s it’s a major contributor to turbulence in the atmosphere that affects aircraft.

Gravity waves form when air traveling up and down in the atmosphere meets resistance. For instance, clouds rising in the troposphere, the lower level of the atmosphere where air mixes freely, will bump up against the boundary of the much more stable stratosphere, forming ripples in the process. Big mountains like the Colorado Rockies often form gravity waves as air flows over the mountains and then overshoots as it reaches the other side.

If you think about it, the theory behind gravity waves make a lot of sense. For example, have you every asked yourself why it’s harder to get out of bed in the morning on some days than others. Or why your weight fluctuates 5-10 pounds? It’s not the extra piece of holiday cake. It’s because you’re being hit with a gravity wave.

Here’s some more travel news you can use:

US Airways has become one of the world’s first airlines to accept MasterCard PayPass-enabled cards and devices to make contactless payments for in-flight purchases. Passengers can tap their PayPass-enabled MasterCard or device on a US Airways’ PayPass-accepting reader to complete a transaction without use of a PIN or signature because of the low-value transactions.

Those who want to see the TSA go away may have their day. The agency has been so widely criticized for its procedures that it didn’t even bother to show up for a House aviation subcommittee hearing last week, as officials seemed fearful of having to answer hard questions and wanted to avoid getting publicly lambasted (again). But the TSA’s absence may have spoke louder than words.

YouTube has reached a new agreement with commercial airline Virgin America that brings web video content to passengers during flights. Beginning Dec. 15, passengers can watch videos from five YouTube channel partners on the small screen that’s in the back of each seat’s head rest. The content includes Warner Brothers’ H+ The Digital Series, WIGS’ Blue, Geek & Sundry’s Written By a Kid, Crash Course, and Barely Political’s The Key of Awesome.
